OTRC: Hayden Panettiere, Mark Sanchez spark dating rumors

Hayden Panettiere of "Heroes" fame and New York Jets quarterback Mark Sanchez were recently photographed walking together outside an In-n-Out Burger in California, weeks after she announced her split from Ukranian boxer Wladimir Klitschko.

Panettiere's spokesperson confirmed on May 12 that the actress and Klitschko had broken up after some two years. Prior to dating Klitschko, Panettiere was linked to her "Heroes" co-star Milo Ventimiglia. The two dated for at least a year and broke up around February 2009.

Panettiere is known for her cheerleader role in the series "Heroes" and recently starred in the film "Scream 4" and the controversial Lifetime movie, "Amanda Knox: Murder on Trial in Italy."
